A successful attempt to incorporate the advantages of severe plastic deformation (SPD) methods in continuous drawing process for low‐carbon steel is demonstrated. The structural features are considered on different scale levels, using a wide range methods. While combining shear deformation, which parallels basis SPD with conventional scheme, cyclic grain refinement could be reached. As result, plasticity becomes enhanced. At same time, an important characteristic such as residual stress also has positive influence manufacturability; particularly, existence compression after deformation. peculiarity structure affects behavior both mechanical and physical properties (like density, plasticity). application (DSh) technology based principles, softening effect observed, healing microvoids. Such affection gives opportunity increase effectiveness through controlling (ductility). In addition, it exhaustion resource (EPR). It shown that case multipass there parabolic dependence EPR measurement, minimum damage achieved specific combination partial reductions.
